* Adds console command, 'predecode-j2k <number of threads>' to load all of the texture assets from the scene and decode the j2k layer data to cache. The work is split between the number of threads you specify. A good number of threads value is the number of cores on your machine minus 1.

* Increases the number of ImageDataPackets we send per PriorityQueue pop and tweak it so that the number of packets is ( (2 * decode level) + 1 ) * 2, and (((2 * (5-decode level)) + 1) * 2).  The first one sends more data for low quality textures, the second one sends more data for high quality textures.
